Staked Silt Barrier for Drainage Ditch

Question on a silt barrier for drainage ditch: I am looking for a silt barrier to prevent silt build up in a drainage ditch near our site. I know that they are usually deployed in deeper water. Do you have any ideas?

Answer: Thanks for contacting GEI Works! I would be happy to help you with this. You are correct that a Type 1 Silt Barrier is usually deployed in water. The standard silt barrier will usually feature a depth of about three feet (3') to control silt and turbidity in calm water locations.

Staked Silt Barrier for Drainage Ditch

For the location that you have described, another option that you might consider is an item known as the Staked Silt Barrier. This barrier will feature all of the same construction as our silt barrier, but will include the addition of stakes. This allow the barrier to handle higher flows of water, while still remaining on the land.

Staked Silt Barrier Application & Use

This silt barrier is designed specifically for storm water run-off and sheet-flow control at job sites and silt & sediment control in water shallower that 30 inches such as road side ditches, canals, shallow ponds and lakes. Often implemented as a BMP (Best Management Practices), these staked barrier have been used along road side ditches, shallow marshes and lakes where a floating turbidity curtain, floating silt barrier or traditional silt fence would not work well.

Staked Silt Barrier Installation

Installation is easy too! To install this BMP, dig an 8 inch deep trench along the desired flow control path placing fill on up slope side of trench. On down slope side of trench install 1"x1" wooden stakes (re-bar of similar) on 6' centers maximum. These are to protrude 36" above the gradient. Unroll the Silt barrier and fasten to stakes with ties - 36 inches attached to stakes and 8 inches in trench (HEMMED EDGE IS TOP). Once entire run is in place and desired flow diversion path is in place then back-fill the 8 inch trench trapping the bottom 8 inches of the silt barrier, effectively creating a runoff seal.
